| disk shm_stats | SMART (Self-Monitoring, Analysis and Reporting Technology) data from ATA disks. |
| disk show | Disk ownership. A list of disks owned by a storage system, or unowned disks. This command is available only for systems using software-based disk ownership. |

| fcstat fcal_stats | Error and exceptions conditions, and handler code paths executed. |
| fcstat link_stats | Link event counts. |
| sasadmin devstats | Statistics for SAS-connected disks: command completion counts, frame in and out counts, error and timeout counts. |

| storage show disk -x | The disk ID, shelf, bay, serial number, vendor, model, and revision level of all disks. |

| sysconfig -h | Displays detailed information about each disk, along with the size displayed in appropriate units (KB, GB, or TB) as calculated using the powers of two. (GB = 1024 × 1024 × 1024) |
| sysstat | The number of kilobytes per second (kB/s) of disk traffic being read and written. |
